摘要
选用深圳市城市轨道交通16号线二期工程安良站—福坑站区间盾构始发加固进行数值研究。用最大加固强度,建立多个加固范围工况,分析加固范围在最大加固强度下的合理取值。经过数值模拟,取工程盾构始发加固范围为3 m较为合理,盾构始发安全。
The initial reinforcement of shield tunnels between Anliang Station and Fukeng Station in the second phase project of Shenzhen Urban Rail Transit Line 16 is used for numerical research.With the maximum reinforcement strength,multiple reinforcement range working conditions are established,and the reasonable value of the reinforcement range under the maximum reinforcement strength is analyzed.After numerical simulation,it is reasonable to set the initial reinforcement range of the shield machine to be 3 m,and the shield machine is safe to start.
